IMPROVEMENT IN GRAlN-SEPARATORS.

Specification forming part of Letters Patent No. 179,252, dated June 27,1876; application filed March 27, 1876. i

To all whom it may concern Be it known that I, WILLIAM H. ASBURY,

of Victory, in the county of Vernon, and in the State of 'VVisconsin, have invented certain .new and useful Improvements in Grain-Separators; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the acoom-- arator, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which Figure l is a longitudinal vertical section of my grain-separator. Figs. 2 and 3 are detached views of parts thereof.

A represents the frame of my grainseparator, provided with an ordinary hopper, B, on top.

In my grain-separatorI use two rota-tin g fans, 0 O, revolving at the same speed, and with a \\"ind-board,1), arranged between them so as to conduct the blast just where needed. If desired, this wind-board may be made adj ustable, and held at any angle desired.

Upon the fan shafts at one side of the machine are secured pinions aa, which mesh with a cog-wheel, E, secured to the inner side of a large fi -wheel, G, mounted on a stud projecting from the side of the frame, and operated by crank or other suitable means.

By this construction and arrangement of the parts a steady and uniform motion of the fans is obtained without any jerking, and by the use of two fans the grain gets a better separation,and obviates the necessity of running the grain through twice, as has-often to be done.

The grain passes from the hopper B onto a screen, I, below which are two other alternately-inclined screws, 1 and I all connected in one shoe, H, which is pivoted at the rear by a pivot-bolt, I), and the'upper front end thereof suspended by means of links 61 d, as shown. The shoe obtains its shaking motion from a crank on the upper fan-shaft connected by a rod with one end of a pivoted elbow-lever, and

It will be seen that the shoe is pivoted at the rear, and vibrates from the front end, so that the sieve will shake the most where the grain first comes on it, and as the grain passes down over the top sieve, I, the movement of the sieve gradually diminishes, thereby separating the oats more thoroughly from the wheat.

The second sieve, I is a seed-sieve, and has a board. or box, J, underneath, with spout J extending through one side of the frame for carrying off such seed as falls through this sieve.

The third sieve, 1 has under its upper end a box, K, with spout K for carrying off the cleaned grain, the imperfectly cleaned grain passing from the sieve I onto a board, L, thereunder, and falls from the same onto a sieve, M, in the bottom of the machine. This last sieve is suspended by hooks eefrom a v sieveM the grain passes into an inclined box,

N, from which it is carried upward by a screwelevator, 0, into a spout,,P, above the hopper B, and down into said hopper, to be passed through the machine over again.

The elevator is operatedby a belt, h, passing around the pulley on the upper fan-shaft, around two idle pulleys, i i, and around a pulley, k, on the upper, end of the elevatorshaft.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The shoe H, pivoted at its rear end, and suspended at the feed end by the books (1, substantially as and for the purposes herein set forth.

2. The shoe H, pivoted at its rear end, suspended at its feed end by the hooks d, and provided with the alternately inclined sieves- I 1 1 as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of February, 1876.
